Patent GB-155592-A (GB)
Title: Improvements in and relating to the synthesis of ammonia
IPC: C01C1/04
Filed: 1920-12-20
Abstract: A catalyst for the synthesis of ammonia consists of an alkali or alkaline-earth metal iron cyanide, e.g. potassium ferricyanide or calcium ferrocyanide, distributed upon a porous support, such as pumice.  The catalyst is "activated" by subjection to a gradually increasing and lengthy heat treatment in a current of hydrogen or nitrogen or both, preferably by gradually raising the temperature to about 360 DEG  C. in the presence of a nitrogen-hydrogen mixture at atmospheric pressure and then slowly raising it to a temperature of about 450 DEG  C. in the contact chamber, whilst a mixture of nitrogen and hydrogen under a pressure of 100 atmospheres is passed in until the issuing gas contains no trace of hydrocyanic acid.  The temperature is not allowed to rise above the limits specified until the close of the activation process, when it may be allowed to remain at 600 DEG  C. for a short time.  The synthesis of ammonia is then begun, the nitrogen-hydrogen mixture under a pressure of 100 atmospheres being introduced into the contact chamber maintained at 450 DEG  C.  The Specification as open to inspection under Sect. 91 (3) (a) states that when the catalyst becomes spent, it may be blown out of the contact chamber by means of a jet of the reaction gases. This subject-matter does not appear in the Specification as accepted.

Abstract: 361,651. Capacitance measurements. HACKETHAL - DRAHT - UND KABELWERKE AKT.-GES., Hanover, Germany. Dec. 10, 1930, No. 37307. Convention date, Dec. 10, 1929. [Classes 36 and 37.] During the manufacture of a cable, a length of quad or other core group is received on a device having means for screening the individual turns of the conductor while the properties of the core group are being measured. As shown in section in Fig. 1 and in perspective in Fig. 2, the core group d to be tested is received on a drum a with grooves b, the drum being either of metal or of wood &c. coated with metal. The starting ends of the cores of the group d are connected to sliprings e, which are connected to the measuring apparatus by brushes f. The surrounding of the core group by metal on three sides facilitates the measurement of the earth capacity and the running capacity. The drum a is located between the take-off disc and the winding stand. While a completed group h<1> is being wound off, the next group h<2> may be wound on, as shown in Fig. 4. In order that the core group being wound on may enter the correct groove, the whole drum may be displaced axially, or the core group may pass through a guide which is moved axially along a bar by engagement with the groove. In order to maintain the core group dry, or to dry it further, heating means may be arranged in the interior of the drum. Instead of a single cylinder, a pair of cylinders as shown in Fig. 7 may be employed. The core group is passed between the two cylinders after the manner of a block and tackle, the straight parts of the groups between the drums being screened by metal sheets or tubes.

Filed: 1963-09-24
Abstract: 1,023,963. Diplex radio singalling; telegraphy. SCANTLIN ELECTRONICS Inc. Sept. 24, 1963, No. 37512/63. Headings H4L and H4P. In an amplitude modulation radio transmission system additional binary signals which have no effect on the amplitude modulation signal are transmitted by the use of small phase shifts of the radiated carrier. The transmitter, Fig. 1 (not shown) includes a conventional master oscillator 10, R.F. amplifier 11, modulator 12 and sound signal source 13. In addition binary signals are supplied to an AND gate 20 and through an inverter 21 to an AND gate 22, both gates being controlled by a multivibrator 23 operating at the information rate of the binary input. The outputs of the AND gates are passed to an OR gate 24 which supplies an output in which a binary one appears as a positive-going change and a binary zero as a negative-going change so that the pulse code has a zero average value. The carrier frequency is controlled by a crystal 30 in series with a capacitor 31 and to provide the required phase variation the capacitor 31 is shunted by the network 33 which includes diodes 36, 37 acting as voltage sensitive capacitors receiving the output of the OR gate 24, the phase being shifted within the range 180 degrees. The sound modulation may be received by a conventional radio receiver. A receiver for the phase modulated binary signal, Fig. 3, comprises conventional stages 50 to 54 feeding an LF signal to a phase detector 55 consisting of a piezo-electric crystal operated between its series and parallel resonance frequencies. The output of the phase detector is supplied via an amplifier and low pass filter 56 to a clipper and amplifier 57 to produce a signal 63, corresponding to the signal from the OR gate 24 at the transmitter, which operates a trigger circuit 58 producing an output pulse for each change in level of the input signal. The output of circuit 58 is supplied via a capacitor 64 to a diode OR gate 65 and also via an inverter 66 to the gate 65. Normally the output of the inverter gate would include a positive pulse for each pulse of the input signal but non- information carrying pulses are blocked from the inverter gate output by pulses 69 fed back from the decoder gate 60 via line 67. The decoder gate 60 comprises a one-shot multivibrator triggered by the output of the inverter gate and arranged so that it cannot be operated in less than one half of a clock cycle after a preceding operation so that it will not follow the double clock frequency pulses which occur when a series of ones or a series of zeros are being transmitted but will follow pulses corresponding to alternate ones and zeros, thus providing the train of timing pulses 69. The pulse train on line 72 corresponds to the binary input signal each pulse representing a one and the pulse train on line 73 represents the binary signal with each pulse representing a zero and these pulses are used to trigger a flip-flop 61 the binary output appearing on line 74 and its inverse on line 75.
